The village is a picturesque mixture of old pink stone and red tile with a dramatic belfy, medieval gateways and defensive walls. Two feudal medieval castles dominate the village and the valley, one of which is the Château de Bruniquel.

The 'old' castle was built in the 12th century on the ruins of an earlier fortress said to have been founded by Queen Brunehaut in the 6th century and remained occupied until the 20th century. It was the home of William of Tudela who wrote the first part of La Chanson de la Croisade Albigeoise, an account of the Albigensian Crusade against the Cathars. The castle is notable for a gallery 20 metres long in Renaissance style overhanging the valley of which it offers steep views that many visitors find alarming.

The 'young' castle was built in the 15th century and occupied for about 200 years. It now houses a museum of prehistory exhibiting "treasures of Bruniquel" found in several caves near the castles.
